Previously, Vasquez had appealed for a stay of execution, but the U.S. Supreme Court declined his petition, Fox News reported. The decision to decline his petition came a mere four hours prior to his scheduled execution and in their statement, the court provided no reason for their decision to decline his petition.

Vasquez was allegedly intoxicated when he killed the 12-year-old boy, David Cardenas.

He told investigators that he heard voices telling him to not only kill the boy, but to drink his blood.

According to a confession from Vasquez, which was videotaped back in 1998, he whacked the boy in the back of his neck with a pipe before slitting his throat. He then picked him up and while he was holding him in the air, the blood dripping on his face, something told him to drink.

The blood was dripping and got it all over my face, so I don’t know. I mean, something just told me drink.
